So, today we managed to get anal sex and a large red penis into the Guardian. All a bit rich for one's blood, really. The piece was a story I wrote about a collaboration between Louise Bourgeois and Tracey Emin, completed before the great French artist died, aged 99, in May. Has Emin pulled off working with Bourgeois as an equal? Or do the words "giant" and "minnow" spring to mind?
